9 Claims. (01. 197-47) It is among the objects of my present invention to provide a toy typewriter which has all the advantages of that of my previous application Serial No. 658,318, filed March 29, 1946 and of my previous issued Patent No. 2,398,765, dated April 23, a

1946, including the use substantially solely of sheet metal and rod stock to simulate the appearance of a genuine portable typewriter and to do so by a structure that is more attractive in appearance, simpler in construction, affording greater convenience in operation and enhanced reliability in use and which has the further advantage over said prior inventions of increased visibility of the typing area of the platen. r

In the accompanying drawings in which is shown one of various possible embodiments of the several features of the invention,

Fig. 1 is a plan view of a toy typewriter according to the present invention showing its general appearance with the simulated keyboard and associated structure in place thereon,

Fig. 2 is a transverse sectional .view thereof taken along line 2-2 of Fig. 1,

Fig. 3 is a view similar to Fig. 2 with the key lever depressed, showing the type wheel in typing position,

Fig. 4 is a transverse sectional view taken on line 4-4 of Fig. 1,

Fig. 5 is a transverse sectional detail view taken on line 5-5 of Fig. 4, and

Fig. 6 is a sectional detail view taken on line 6-6 of Fig. 5. i 5

Referring now to the drawings, the toy typebracket 2| having a pair of upstanding arms 22, 23 at opposite ends on each side thereof. Key lever 20 is pivoted on an axle 24, the latter being journalled in arms 22 of the bracket 2|. Each of the arms 25 of the key lever 2|] is pivoted to a link 26, the upper end of said link being pivoted by means of axle 21 to the obliquely extending arms 28 of a substantially U-shaped sheet metal carriage 29. The end of each of said oblique arms 28 is pivoted to upstanding arms 23 on standard 2! as at 59.

Depending from carriage 29 is a U-shaped bracket 30, the arms of said bracket being affixed to the carriage 29 as at 3!. A type wheel .32 having at its periphery the type heads comprising the sequence of letters and numerals, is aflixed to the upper end of a substantially upright axle 35, the latter in position of rest being :at substantially right angles to platform l6 and journalled in bearing openings 33, 34 in bracket 30 and carriage 29 respectively and protruding from writer simulates the general appearance of a modern portable typewriter, presenting as it does a base H, a simulated standard keyboard 12, a housing l3 to the rear thereof of the shape and dimensions commonly used on standard typewriters to enclose the key lever basket and the ribbon mechanism, and a platen structure It to the rear of the housing.

The sham keyboard and housing are preferably of a single sheet metal stamping, the housing portion being divided as at l5 to accommodate the main operating parts of the toy typewriter which are mounted on an oblique rectangular platform l6 which is a unitary part of the base. The platform has a shortfront wall I1, a higher rear wall l8 and trapezoidal side walls l9.

Protruding from the divided portion l5 of the housing is a single U-shaped key lever 20, depression of which effects the typing operation by the means hereinafter described.

Upon the middle of the platform It is afiixed a standard. preferably a U-shaped sheet metal the reversely turned extremity of the lever.

the latter.

The type wheel 32 is adjusted to a selected setting by means of a rotatable dial knob 36 which bears the sequence of letters and numerals on its upper surface. Thedial knob is affixed to the upper end of shaft as by force fit in its hub 35 and its upper surface is exposed at the exterior of the housing l3, as best shown in Figs. 1 and 4. Ratchet means is preferably provided to step the type wheel aroundin effective setting thereof by the turning of dial knob 36. A pointer which indicates the selected setting is positioned so as to be near the periphery of said knob. It is aflixed to a cover plate 29', the latter being supon the dial knob and type wheel.

Coasting with the ratchet wheel is a pawl lever in which is pivotally mounted at one end to bracket 3i! and which bears a pawl roller 4! near its opposite end urged by coil spring 42 into engagement between the teeth of the ratchet. The pawl roller 4! is preferably pivoted on a pivot 43. as best shown in Fig. 6, in a clevis formed between the main length of the pawl lever and The coil spring is preferably anchored at one end to pivot 43 at the roller end of the pawl lever and escapementbox 6il at the other.

. 3 at its other end to the lower end of axle 35 on which the type wheel and dial knob are mounted.

For applying ink to the type head, an ink retaining absorbent roller 44 which is itself conventional is preferably provided. This roller is mounted on a bail 49 integral with and extending outward from the midsection of the cross-arm of a substantially U-shaped bracket 45, the arms 45 and 41 of which are pivoted to the carriage 2b as atABi' The; extension 46! of arnr 46iscon.- nected by pitman=58 to-arm 2-2 of bracketZl for the purpose hereinafter described. The bail 49 has a slot 5| in each of its cross-arms 50. Mounted in said slots 5i is a wire spring holder 5l with= two legs 53 and 54 resiliently urged apart by the connecting loop 56.

Leg 54 extends. through. a sleeve 51 upon which the inkroller 44 .is mounted;

Accordingly, the spring holder may readily be withdrawn for replacement of the ink rollereasu required. In the normal or idle position of the machine, the: ink roller, is engagement; with the typefwheel. as. best shown in. Figs. 2 l and-4.

The escapement structure is quite similar to that. of my above. identified issued patent. and need therefore be but. briefly described; The escapement. box 60,- is-i conventional. andits interior. partsarenot shown. Its protrudingipawls fi l. coact withan indented rackli-Z (Figs. Zand 4 on the base; of theplaten structure. The-escapement is operated. from. a: cam. plate, 63 freely rotatable about the axle 24 of the key-lever and connected by a wire, link Gdhooked at.65-to plate at, one end: and to. the mechanism in the A link. 66 pivoted. at. one end to. carriage 2.9. on. axle 21, and

having. a stud; 8.7.. atv its other end. riding in an farcuate; slot 6min: thev cam plate causes thelatter to be-pivoted by thedepression stroke of the key lever 20, thereby to'. pullllinkv 64 forward for the escapement. action.

The, spacer. lever. 69. protruding through the forward part of the platform I6 is. pivotally anchored.- at its rear end.as=at.10 tothe. rear wall 58.... An upstanding link. H. is pivotally, connected at its lower end tospacer lever, 69v asat'lz;v The upper end offlink ll'i's pivotedlin anarcuate. slot .lii'in cam plate. 63.'into.which=slot.it-ishooked as. at 14; riding, idly therein. when. key lever 2'0 is depressedand actuatingthe escapement mechanism through link 64, when spacing leven 6-9. is .jdepressed.

The operation may be briefly summarized.v The dial knob 351s first-turned" to the desired. letter or numeral'as indicat'edby the pointer. 55. This turnsv the. type. wheel 32 which is afii'xed to. the same'axle seas is, the dial" knob. In reachinglthe desired setting, the ratchet wheel 37,, which, is also keyed'on axle. 35" ratchets over the roller. 4! of the spring urged'pawl lever 4ll,"the. latter re:- siliently holding the ratchet, wheel and with it, the type wheel. 32, in the set position. Key lever zfi'is now depressed, causing it. to pivot aboutaxle 24; The thrustltransmittedifrom the keylever through. links 26.170 carriage 29 causes the latter to pivot upwardly about. its pivots 59 from the standby position shown in Fig. 2to the position shown in Fig. 3, bringing the type wheel 32 in contactiwith the paper on the platen i4.

In the course of the depression of thekeylever 25, bracket 45 carrying roller, 44 is pivoted" by means of'pit'man' 58 causing roller 44' mm raised, inking a few of the type heads including. the one to-be imprinted during its. upward motion, and then clearing the type. wheel and the. platen.

Depression of key lever 20 also causes link 66 to be moved toward the platen l4 by the transmission 26, 21, thereby causing cam plate 63 to turn in a clockwise direction, as seen in Figs. 2 and 3 through the transmission 61, 6B. This will cause link 64 to be pulled, thereby moving the platen forward one space.

Release of the key lever will allow the carriage to pivot to its idle position, as shown in Fig. 2, solelyby virtue: of the-weight of the carriage. Return of the carriage will also cause the bracket 45 to pivot downward to the position shown in the. type wheel.

The spacer lever 69 when depressed, will cause link'lflstoirotate the cam plate causing the escapementmechanism to function. Due to the lost motion slot 68, depression of the spacer lever will have. no: effect on carriage 29.

As many changes could be made in the above constructionand many apparently widely different embodiments of. this: invention couldtbe made without. departingv from the scope of the. claims, it. is intended] that. all: matter; contained: in the above. description or: shown. in .the accompanying drawings shall i be interpreted as illustrative and not. in alimiting sense.
